Sarah, Duchess of York feared she had been handed a "death sentence" when she was diagnosed with breast cancer
The 64-year-old royal - who was married to Prince Andrew from 1986 until 1996 and has daughters Princess Beatrice, 36, and Princess Eugenie, 34, with her - underwent a single mastectomy after being diagnosed with the disease last June and explained that her mind went to the "darkest places" when she initially received the news.
